  • Powder characteristics and morphology

    Powder for Additive Manufacturing

    Osprey® metal powder for Additive Manufacturing is characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.

    For blown powder processes, such as Direct Energy Deposition (DED), good flow ensures uniform build rates. Tight control of the particle size distribution also helps ensure good flowability. Low oxygen powders result in clean microstructures and low inclusion levels in the finished parts.

    Powder for Metal Injection Moulding (MIM)

    Osprey® MIM powder has a spherical morphology, resulting in high packing density. This enables the manufacture of feedstocks with high powder loading, which not only minimizes binder costs but also reduces part shrinkage during debinding and sintering. Spherical powder also has excellent flow characteristics, resulting in reduced tool wear and consistent mould filling.

    Osprey® MIM powder's low oxygen content allows better control of carbon and consistency during sintering. Low oxygen levels, together with high packing density, also facilitate faster sintering.

  • Particle size distribution

    Powder for Additive Manufacturing

    Osprey® metal powder for Additive Manufacturing is available in a wide range of particle size distributions that are tailored to the individual Additive Manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.

    Typical particle size distributions for Additive Manufacturing.

  • Sintering

    Osprey® PANACEA has been industrialiZed for MIM, which has a defined production process including sintering temperature and time profile.

    • Sintering at atmospheric pressure: 1000mbar 75% N2/ 25% H2
    • Partial pressure sintering: 800mbar 100% N
    • Typical sintering cycle: 5 K/min to 600 °C, 1 h hold, 600 °C, 5 K/min to 1250 °C, 6 h hold at 1250 °C, then cooling as fast as possible

    A post-sintering solution anneal and a rapid cooling (>150 °C/min.) based on an inert gas quench is necessary to create an austenitic microstructure (non-magnetic) and avoid surface chromium nitride precipitation.
